since you are new to skiing you probably want an entry level to intermediate level park ski, a higher level park will not make you progress better, as it will be heavier and harder for someone just getting into skiing to use. I ski out east too, and I found that mid 80's is a good waist width to start out at, both in park and all mountain.
if you are buying locally, most shops will carry an entry level park ski. some local shops might have some good deals on these skis in the late spring and summer. line masterminds, k2 press, volkl alley, and nordica badminds are some good options to start off with, though they wont have the best durability and performance once you start throwing bigger tricks.
If you are confident enough with you skiing an intermediate ski would not be a bad choice either. you will get better construction and durability, but they will most likely be a bit stiffer and heavier. some good options are line afterbang, Armada el rey, atomic infamous, and k2 sights.
for bindings, see if you can grab a pair of marker squires or rossignol axial 120. you don't have to worry about outgrowing bindings, just don't go set them to max din right away and these bindings will do fine. and boots, get whatever boot fits man.
If you consider yourself a beginner skier wait a few months and start looking for some deals on entry level park skis and equipment at the local shops. if you want gear soon and are feeling comfortable enough to get some intermediate park skies, I recommend the k2 sights with rossignol axial 120 bindings. they are going for a great deal on the Evo outlet websight right now. check Evo.com out and get to know the brands in the industry.
